Abstract (en)
[origin: WO2021021429A1] An ear-worn electronic device comprises a housing configured to be supported by, at, in or on an ear of a wearer. Electronic circuitry is disposed in the housing and comprises a processor. A power source and a receiver or a speaker are respectively disposed in or on the housing. A microphone array is disposed in or on the housing and operatively coupled to the electronic circuitry. The microphone array comprises a plurality of microphones. The processor is configured to operate a set of two or more of the microphones in a directional mode, detect degradation in performance of any microphone of the microphone set, and switch microphone operation from the directional mode to a safe mode using at least one non-degraded microphone of the microphone set in response to detecting the microphone performance degradation.
